What this part is and where it fits
The LMH0034MA is a line equalizer from National Semiconductor designed for serial digital video interfaces. It compensates for signal loss over coaxial cable in broadcast and professional video links operating at SMPTE 292M (HD-SDI) and SMPTE 259M (SD-SDI) data rates. Housed in a standard 16-SOIC narrow-body package (3.90 mm width), it mounts on the PCB via surface-mount assembly. The supply rail operates from 3.135 V to 3.465 V. The serial interface means it handles one differential video channel per device, typical for the receive side of an SDI BNC input. It is not a multi-channel reclocker or deserializer — it is the front-end equalization stage before the signal hits the deserializer.
Package and handling note
The 16-SOIC footprint is common, but verify your solder paste stencil aperture for the 0.154" body width.
Lifecycle and compliance
Critical note: this part is RoHS non-compliant. If your assembly line is RoHS-exempt for certain applications (e.g., military, aerospace, or medical with leaded solder exemption), it fits. For standard RoHS-mandated consumer or telecom builds, you will need an exemption or a lead-free alternate.
